Hoping to shore up a $58 million budget shortfall, Oakland Mayor Jean Quan announced a plan that would "share the pain" among the city's employees and residents - pay concessions from city workers, including police and firefighters, and a new voter-approved parcel tax to boost revenue.

"If we don't get contributions from city employees and we can't get residents to approve a parcel tax," Quan said Friday at City Hall, "the worst-case scenario looks bad."

Quan and city advisers laid out three budget options she'll present Thursday to the City Council, which is expected to cast a final vote in June.

Yet it was clear Quan was pushing for option C: the version that includes passage of her proposed parcel tax, which the City Council blocked two weeks ago.

If Quan can get the council to agree to place the parcel tax on a ballot, residents could vote on whether to pay higher taxes by this summer.

The mayor has said the temporary, five-year, $80-per-parcel tax measure will bring in an estimated $11 million a year to the general fund.

City Administrator Lamont Ewell said the compromise plan was the best way to "chart out a course based on reality" after five years of contracting the city's budget. With the uncertainty of state and federal funds coming to Oakland, Ewell said the plan favored by Quan gave the city a chance "to return to the good times."

No matter what option the council selects, Quan said police staffing will remain at current levels, and all elected officials will take a 15 percent pay cut.

In scenario A - the scorched-earth option that would rely solely on cuts to city services - the shortfall would be cured by eliminating 368 full-time positions, the closure of four fire stations and four major libraries, and the shuttering of five recreation centers. Public works would lose 25 jobs, and funding to several of the city's cultural programs - Fairyland, the Oakland Zoo, the Film Office - would be eliminated.

In option B, Quan's administration outlined a budget that relied on a mix of service cuts and "employee contributions" - staffing and pay cuts taken on by the city's work force through furloughs and concessions from the city's unions. The city would lose 145 full-time positions, some fire stations would close during the winter, and the library budget would lose $400,000.

That option will take some political maneuvering, as Quan continues to negotiate with the city's five largest unions, including police officers and firefighters.

"Everyone is at the table, and the negotiations are going well," Quan said.

On the same day City Attorney John Russo officially accepted the position of Alameda city manager, Quan said she was surprised to learn the city had spent more than $700,000 arguing for and defending the controversial gang injunctions.

Quan said she would pursue a policy that requires the next city attorney to get approval from the City Council for cases in which legal fees escalate beyond $100,000.

"There have been some cases where the costs ballooned and we didn't know it," Quan said. "I would have rather spent the (gang injunction) money on gang-prevention programs."
